Smc Pneumatics KQ2H07-34AS Push-to-connect Fitting 1/4 Od

Product Description

The SMC PNEUMATICS KQ2H07-34AS is a push-to-connect tube fitting connector designed for fast, tool-free tube connections in pneumatic plumbing systems. It accepts tubing with a 1/4 inch outside diameter and threads into ports with a 1/8 inch NPT male thread. The body is constructed from brass with polybutylene contact components and is rated to 145 psi maximum working pressure. Operating temperature range spans 23 degrees F to 140 degrees F, making it suitable for a wide range of indoor compressed-air and fluid-conveyance applications. HVAC technicians, plumbers, and pneumatic system installers use this style of fitting where quick assembly and reliable sealing are priorities.

This fitting is suited for residential and light commercial pneumatic control lines, instrumentation tubing runs, and compressed-air distribution systems. The push-to-connect design eliminates the need for ferrules or compression tools, speeding up installation in tight equipment cabinets or control panels. Its NPT thread base allows direct connection into standard ported manifolds, valves, solenoids, and actuators common in HVAC controls, building automation, and fluid-handling equipment.

Compatibility

Designed as an OEM-style push-to-connect connector for pneumatic tubing systems using 1/4 inch OD tubing and 1/8 inch NPT threaded ports.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or pneumatic system technicians. Before servicing any pressurized line, depressurize and isolate the system fully. Ensure the receiving port threads are clean and apply thread sealant appropriate for the service fluid per local codes. Tubing should be cut cleanly and squarely before insertion to ensure a proper seal within the collet.
